“Behind Mansion Walls” tells the stories of crime, mystery, and murder that unfold behind the veil of wealth and privilege. Secret affairs, hidden accounts, and false identities are just the tip of the iceberg in a world clouded by money that could lead to murder. Hosted by society columnist Christopher Mason, this series uses expert testimony, stylized recreations, and narration from the victim’s first-person perspective, escorting viewers behind picture perfect facades, where greed leads to murder and no one is above the law.
